elasticsearch 如何在Elasticsearch 7.5中过滤嵌套对象?
我有一个映射:
elasticsearch 如何在Elasticsearch 7.5中过滤嵌套对象?,
elasticsearch,filter,nested,date-range,
elasticsearch,Filter,Nested,Date Range,我有一个映射: "ntol-2020-05" : { "mappings" : { { "properties": { "_createdAt": { "type": "date" }, "_logType": { "type": "text",
"ntol-2020-05" : {
"mappings" : {
{
"properties": {
"_createdAt": {
"type": "date"
},
"_logType": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"device": {
"properties": {
...
}
},
"resp": {
"type": "nested",
"properties": {
"data": {
"type": "nested",
"properties": {
...
}
}
}
}
}
}
}
}
}
我使用三个条件进行筛选:
- “日志类型”是“爬虫”
- “2020-05-23”上的“创建数据”
- “resp”的大小=0
"type": "script_exception",
"reason": "runtime error",
"script_stack": [
"org.elasticsearch.search.lookup.LeafDocLookup.get(LeafDocLookup.java:94)",
"org.elasticsearch.search.lookup.LeafDocLookup.get(LeafDocLookup.java:41)",
"doc['resp'].size() > 0",
" ^---- HERE"
],
"script": "doc['resp'].size() > 0",
"lang": "painless",
"caused_by": {
"type": "illegal_argument_exception",
"reason": "No field found for [resp] in mapping with types []"
}
}
如果我使用script“doc.containsKey('resp')&&doc['resp'].size()>0”
,那么它将返回hits length=0
帮帮我。谢谢
您可以使用exists返回“嵌套”字段“resp”有值的文档
{
"query": {
"bool": {
"must": [
{
"nested": {
"path": "resp",
"query": {
"bool": {
"filter": {
"exists": {
"field": "resp"
}
}
}
}
}
}
]
}
},
"from": 0,
"size": 10
}
